Overview

This scoping review identifies 82 factors influencing the trustworthiness and credibility of digital nutrition information from the perspective of young adults, based on a review of 48 papers.

Background

The internet has become a primary source of health information for young adults, with many actively seeking nutrition-related content online. This review examines how various factors, including ethnicity and education, influence perceptions of digital nutrition resources.

Data Highlights

Key Findings

  • 48 papers were included in the review, identifying 82 factors related to trust and credibility.
  • The most frequently reported factors were clarity of information (n = 14), prior background knowledge (n = 13), and receiver's education (n = 7).
  • Only 25% of the papers included a multi-ethnic sample, indicating a lack of diversity in research.
  • 46 additional factors not covered by existing frameworks were identified.
  • 75% of the papers did not report the ethnicity of study participants.
